I'd like to connect to this gas line (the bigger top one) for an improvised outdoors burner. This was originally connected to a gas control valve. It's weird in that it needs a male flare but a female thread, which I have not seen as standalone fittings so far. This will be low pressure gas, so in a pinch I could cut off the female flare and just put flex tubing on the stub with a hose clamp like is done for outdoors propane lines sometimes, I guess, but that's not very satisfying. This seems to be SS so regular soldering may not be an option, I imagine. Silver soldering or brazing, maybe, but not proficient at that, unfortunately. Maybe reset the end to a flare after replacing the threaded male nut with a female one? I've got flare formers, but not proficient at that either. Oddly, looks like the thread is likely not a standard flare fitting thread either, this one is 18 TPI. Or cut the end off and make ample use of epoxy / silicone to seal a tube on there? Or use a compression fitting (the OD of the straight stub behind the flare is 1/2" within a couple of thous)? To clarify, this will be used outdoors so not as critical as indoors if I were to improvise something.
Or do you know of a fitting that would work?
added: the more I think about this, the more it seems that a compression fitting would be easiest. Cut off the existing flare, put a compression fitting on the 1/2" OD stub, use a 1/2" female compression to NPT fitting and done. If I do that, wouldn't a plastic ferrule be OK for this given the very low pressures? Heck, I could probably use a pneumatic push-to-connect fitting for that (so lucky it is a true 1/2" OD...) if it's not too scratched up. (But questionable possibly, as you really want to use flares for gas, though I would of course test for leaks regularly.)
